blower speed to provide improved comfort, quietness, and potential
energy savings. The graph below shows the ramping process.
lower right side of the board. The dip switches work in pairs to select
the cooling/heat airflow (CFM/TON), and Fan off-delay options.
ICM FAN MOTOR ADJUSTMENTS
If the airflow needs to be increased or decreased, see the Airflow
Table in the Service Facts. Information on changing the speed of the
blower motor is in the Blower Performance Table.
Blower speed changes are made on the ICM Fan Control mounted
in the control box. The ICM Fan Control controls the variable speed
motor.
There is a bank of 8 dip switches, (See Figure 15), located at the
upper right side of the board. The dip switches work in pairs to match
the cooling/heat pump airflow (CFM/TON), Fan off-delay options,
and electric heat airflow adjustment. The switches appear as shown
in Figure 15.
